    Hope to do some long term tracking on just the new 2016 Touring tires for Bridgestone/MIJ/OEM.
    Ecopia EP 422 Plus P215/45/R17 87V A Traction A Heat 600 Tread Wear

    Interested in 10K, 20K, 30K, 40K, and 50K wear data and any factory defects.
    Also the PSI you run and rotation schedule if you have one.

    Thread will be updated as I figure out how to do the poll cats.

    May do a spread sheet with results or see if we can add a second poll.

    Also just assume all tires have the same pressure. The focus is the new OEM tires on the 2016 Touring but all touring data would be appreciated.

    Thanks,

    I settled on 36 psi with our (17") Pilots. Seems a decent compromise.

    The poll should specify front tires... or back... or all around. I guess that's too many options.

    @ETP maybe you can clarify in your initial post, that it's the 17" low profile tires that come on "Touring"? I'm guessing the 42 psi responders have 15" tires.

    If you could change the poll cat title to "Touring 17" Low profile OEM tires only" "assume all tires have equal pressure"

    Also could delete the 35PSI and add 44PSI.

    There is no place to differentiate between front and rear unless there were two polls. Don't think I can do two polls. Not sure how to do this eh! Maybe just say front tires?????

    I think it's all good. Yeah you could say front (or both) tire pressures. FWIW I use the same all round.

    You can edit the thread title, say to qualify it as 17" poll, being the OP. There's a button at top of page.

    @Danny it took four attempts to post this. :(

    I can change the main title but not the poll stuff. Also on an older thread the title cannot be changed. Must be some sort of time restriction or size of thread.

    Unfortunately it will not allow all that. Really need two polls.

    Maybe but many of us are doing 42 PSI

    Ok.

    I run 17" except 15" XIce in winter. I set the 15" around 42, but the 17" would be very firm at same pressure, set them lower, at 36. They're still firmer there.

    Plus, with the 17", between 42 and 36 there seems to to be little or no drop in mpg.

    I hear you loud and clear and most likely spot on. That is why I want a long term results thread. I think wear is the biggest issue but would like to confirm this in a pretend scientific manner.:ROFLMAO:
    So the question is do you want 70-80K tires at 42 PSI or 50K at 36 PSI. :DTBD. Smooth roads 42 PSI does not mater but rough roads is another issue.

    I have compromised and no longer run 44PSI or 51 PSI as the liabilities out weigh the benefits.

    42, the Answer to the Ultimate Question of Life, the Universe and Everything. This Answer was first calculated by the supercomputer Deep Thought after seven and a half million years of thought. This shocking answer resulted in the construction of an even larger supercomputer, named Earth, which was tasked with determining what the question was in the first place.

    The Earth was destroyed by the Vogons five minutes before its ten-million year program was due to be completed. One of the only two humans who had survived the destruction of Earth, namely Arthur Dent, pulls random Scrabble tiles from a bag. When his friend, Ford Prefect, lines up the tiles, they spell, 'What do you get when you multiply six by nine?' Some readers of Adams have thought that this question was the aforementioned Ultimate Question. After all, it is Arthur who has been led to reveal this answer; Arthur is indeed from Earth; the Earth was the giant computer built to work out exactly what the Ultimate Question was; and 'what is 6 x 9?' is a bona fide question.
    Wonder how long the Prius is????


    Really long boring answer=
    • It is a Catalan number.[3] Consequently, 42 is the number of noncrossing partitions of a set of five elements, the number of triangulations of a heptagon, the number of rooted ordered binary trees with six leaves, the number of ways in which five pairs of nested parentheses can be arranged, etc.
    • It is the number of partitions of 10—the number of ways of expressing 10 as a sum of positive integers (note a different sense of partition from that above).
    [​IMG]
    The 3 × 3 × 3 magic cube with rows summing to 42.
    • Given 27 same-size cubes whose nominal values progress from 1 to 27, a 3 × 3 × 3 magic cube can be constructed such that every row, column, and corridor, and every diagonal passing through the center, is composed of 3 numbers whose sum of values is 42.
    • It is the third pentadecagonal number.[4] It is a meandric number and an open meandric number.
    • It is conjectured to be the scaling factor in the leading order term of the "sixth moment of the Riemann zeta function". In particular, Conrey & Ghosh have conjectured that
      1 T ∫ 0 T | ζ ( 1 2 + i t ) | 6 d t ∼ 42 9 ! ∏ p { 1 − 1 p } 4 ( 1 + 4 p + 1 p 2 ) log 9 ⁡ T , {\displaystyle {1 \over T}\int _{0}^{T}\left|\zeta \left({1 \over 2}+it\right)\right|^{6}\,dt\sim {42 \over 9!}\prod _{p}\left\{1-{1 \over p}\right\}^{4}\left(1+{4 \over p}+{1 \over p^{2}}\right)\log ^{9}T,} [​IMG]
      .
      where the infinite product is over all prime numbers, p.[5][6]
    • 42 is a Størmer number.[7]
    • 42 is the only known value that is the number of sets of four distinct positive integers a, b, c, d, each less than the value itself, such that abcd, acbd, and adbc are each multiples of the value. Whether there are other values remains an open question.[8]
    • 42 is a (2,6)-perfect number (super-multiperfect), as σ2(n) = σ(σ(n)) = 6n.[9]
    • 42 is the resulting number of the original Smith number (4937775 = 3 × 5 × 5 × 65837): Both the sum of its digits (4 + 9 + 3 + 7 + 7 + 7 + 5) and the sum of the digits in its prime factorization (3 + 5 + 5 + (6 + 5 + 8 + 3 + 7)) result in 42.
    • The dimension of the Borel subalgebra in the exceptional Lie algebra e6 is 42.
    • 42 is the largest number n such that there exist positive integers p, q, r with 1 = 1/n + 1/p + 1/q + 1/r
    • 42 is the smallest number k such that for every Riemann surface C, #Aut(C) ≤ k deg(KC) = k(2g − 2) (Hurwitz's automorphisms theorem)
    • In base 10, this number is a Harshad number[10] and a self number,[11] while it is a repdigit in base 4 (as 222).
    • 42 is a perfect score on the USA Math Olympiad (USAMO)[12] and International Mathematical Olympiad (IMO).[13]
    • 42 is the maximum of core points awarded in International Baccalaureate Diploma Programme.
    • 42 was when ETP was in full strength.

    Yeah, just don't panic. :)

    I suspect higher tire pressures are tougher on suspension components too, could lead to earlier failure.

    The 2009 had done well at 100k. But had very fast wear with the michelons over the OEMs. 42 psi on the touring and 44psi for a long time. Your mozzarella may vary.
    Tried to reply 15 times on an iPhone and no worky GI. Oh one must have got through. :ROFLMAO::LOL:
    Well the 2009 Touring Four was at 44 PSI and 42 PSI most of its life to 100K at trade. Can't say if anything in the suspension was bad. But the only tires to wear right were the OEMs MIJs. The Michelins wore out the perpendicular tread to where it looked like a front tractor tire. Good parallel tread depth but no cross tread of any kind. Several mechanics said it was the strangest thing they ever saw.
    Obviously a very poorly designed tire.

    Thought I could do better than OEMs and bought the tire recommended in this forum tire thread and TIRERACK.

    There are so many variations of tires by model, place of manufacture, ingredients of the day, and who runs the tire molding machine.

    That is why I am so hot on OEMs MIJs at a proper PSI. Have never found anything better and have tried many times to find a better tire.

    Had a weird experience with Goodrich tires on a Honda. Put two on the back and my MPG went way up. So I thought I will put two on the front. MPG dropped like a rock. Seems the back on a Hybrid could use a different tire and get away with it but not the front.

    I tried 19 times in another thread. Not sure what worse, that, or how dang hooked we are, lol.

    Coming up on my 10K check for both 2016s. No noticeable tire wear at 42 PSI.

    After my daughter lost a tire due to road hazards on the 2011 (that I gave her) I am starting to panic on no spare and no new tire hanging in the garage as an R&R.
